Eastbound Interstate 10 approaching Exit 255, Junction
Northbound Arizona 77. Prior to 1997, this was also an
exit for eastbound Business Loop I-10. The business route
served downtown Tucson via Miracle Mile, Oracle Road,
Speedway Boulevard, and the Stone Avenue/6th Avenue couplet,
following old Arizona 84 and U.S. 80. The business route
was eliminated when maintenance of the downtown streets
was transferred from the state to the city. Photo taken 01/13/06.

This interchange was where old Arizona 84 and Arizona 84A separated prior to 1964, and was reconstructed in 1995 with this elaborately decorated overpass, as part of a 1996 reconstruction project along Interstate 10 through Tucson. Photos taken 01/13/06.

and Interstate 19. Photo taken 01/13/06.
